If you need to protect yourself from yourself, like I needed to do. Then this simple notepad replacement executable may be for you .
Click here to download.
What it does is:

Always instantiates exactly one blank/new/untitled notepad instance at a time.

The untitled stuff is kept in a user configurable file. So you are not constantly bothered with a Save as dialog..

Easily 'dispatch' selections within your notepad to separate files.

When called to open a file, does open a new editor for that file. That editor is configurable.

Supports better CTRL+Z, CTRL+Y than default notepad.

Supports CTRL+F and search next with F3.

(For goto-line with CTRL+G you'll have to dispatch the text to another editor!)

When you own New text document (1).txt until New text document (19).txt, asdf.txt, jlksdjflkajsd.txt, etc., on your desktop. Then you have the same problem I had: using notepads for storing temporary buffers and things like that. With this replacement you are forced to keep just one buffer, which is automatically saved with CTRL+S. And when you do want to keep specific stuff, you select that text and CTRL+D (dispatch to file).
